[Problems to be solved by the invention]
However, as in the above example, the joist supports according to the prior art often have a high height from the floor base to the floor surface.For example, the height space from the floor base to the floor surface such as a balcony is high. In a floor structure having no excess, a joist support as shown in FIG. 8 is not always appropriate. Conventionally, in a floor structure having a small space up to such a floor base, as shown in FIG. 9, as shown in FIG. The height and the horizontal were adjusted by inserting a spacer between the joists and the joists as needed, and a floor board was laid on the upper surface of the joists in general. However, in such a conventional method, there are problems that the man-hour is required for the joist assembly, and that the operation is complicated because the level is adjusted by inserting a spacer between the joist assembly and the joist plate.

It is characterized by having a joist support having a nut member for integrally fixing the angle member, and a floor plate member having each end held by two adjacent joists.
[0012]
【Example】
The joist support and the floor member of the present invention will be described with reference to the drawings.
[0013]
FIG. 1 shows the cross-sectional shape of the joist used in this example. The joist 10 has a cross-sectional shape having a flange portion 12 for supporting a floor plate member extending in the longitudinal direction and a locking groove 13 (encircled by a dotted line in the figure) for supporting a floor plate member extending in the longitudinal direction on opposite side surfaces 11. In this example, an extruded aluminum member was used.
[0014]
FIG. 2 shows an outline of the joist support tool to be engaged with the joist 10. FIG. 2 is a perspective view showing the configuration of the joist support 20. The joist support 20 includes a pair of locking bolt members 21, a joist support main body 22, a pair of adjustment angle members 23, a position adjusting screw 24, and a pair of nut members 25.
[0015]
The locking bolt member 21 has its head 21a housed and engaged in the locking groove 13 of the joist 10, and inserts the joist support tool main body 22 and the adjusting angle member 23 through the male screw portion 21b to screw the screw member 25. They are fixed together by joining.
[0016]
The joist support tool main body 22 is a member that is held on the floor base 1 such as concrete or soil and supports the joist 10, and as shown in FIG. 3, a pair of upright wall portions 26 and the upright wall portions 26 are integrally fixed. The base 27 is formed. The pair of standing wall portions 26 define a joist storage groove 28 such that a portion of the joist 10 below the flange 12 can be inserted and removed. The upright wall portion 26 has a slit 29 at the upper end opening at the center thereof. Since the slit 29 is a guide groove through which the locking bolt member 21 is vertically movably inserted, it may be a vertically long slot. The base portion 27 has a flange portion 27a protruding to the side opposite to each other beyond the standing wall portion 26, and supports a lower end portion of the position adjusting screw 24.
[0017]
The adjusting angle member 23 has an L-shaped cross section as shown in the perspective view of FIG. 4, and has a through hole 31 through which the locking bolt member 21 is inserted at the center of the vertical portion 23a, and an end of the horizontal portion 23b. It has a female screw hole 32 to be screwed with the position adjusting screw 24.
[0018]
The position adjusting screw 24 is screwed with the adjusting angle member 23, and the tip of the screw portion 24 b is supported by the flange portion 27 a of the joist support tool main body 22. By rotating the position adjusting screw 24, the adjusting angle member 23 can be moved up and down relatively to the joist support body 22. Since the locking bolt member 21 engaged with the joist 10 is inserted into the through hole 31 of the adjustment angle member 23, the height of the joist 10 can be adjusted relative to the joist support body 22. . It is desirable that the head 24a of the position adjusting screw 24 has a hexagonal or cross-shaped recess so that the position can be easily adjusted from the upper part of the floor. In the present embodiment, the joist support 20 using four adjusting screws 24 has been exemplified. However, the position adjusting of the joist 10 does not necessarily require the four adjusting screws 24, and at least one or more adjusting screws 24 are provided. Just fine.
[0019]
In order to attach the joist support 20 to the joist 10 of this embodiment, the following procedure may be used. First, the position adjusting screw 24 is screwed into the female screw hole 32 of the adjusting angle member 23. Next, the locking bolt member 21 is inserted into the through hole 31 of the adjusting angle member 23, and further engaged with the slit 29 provided in the standing wall portion 26 of the joist support device main body 22, and the male screw portion of the locking bolt member 21 is formed. A nut member 25 is screwed to 21b, and an adjustment angle member 23 screwed with a position adjusting screw 24 is brought into contact with the upright wall portion 26 to form the joist support 20.
[0020]
The joist support 20 assembled as described above is inserted from the end 10a of the joist 10 such that the head 21a of the locking bolt member 21 is housed and held in the locking groove 13 of the joist 10. The height and level of the joist 10 are adjusted by the position adjusting screw 24 of the joist support 20 inserted into both ends of the joist 10. When the position adjustment is completed, the nut member 25 is further tightened to integrally fix the locking groove 13 of the joist 10, the upright wall portion 26 of the joist support tool main body 22, and the adjustment angle member 23.
[0021]
As described above, by using the joist support 20 of the present embodiment, the joist 10 can be easily arranged on the floor base 1.
[0022]
FIG. 5 is a schematic side view of the floor member of the present invention laid on the floor base 1. The floor member 40 includes at least two joists 10, a joist support tool 20 that supports these joists, and a floor plate member 41. The floor plate member 41 is supported by the flange portion 12 of the joist 10 and can be fixed to the joist 10 by the holding member 43 and the fixing screw 42.
[0023]
By connecting and laying the floor members 40 having such a configuration, for example, a balcony as shown in FIG. 6 can be easily laid. FIG. 6 is a schematic plan view showing the arrangement of joists 10 of a balcony 50 having an inverted L-shaped floor surface projecting from a building 51. The joist coarse material is cut into joists 10 having a desired length, and joist supporting members 20 are locked at both ends, and are arranged on the floor base 1. A balcony 50 can be formed by laying a floor panel member (not shown) between the joists 10.
[0024]
The joist supporting device 20 of the present invention can also be suitably used for joists having a cross-sectional shape in which the locking groove is only on one side of the side surface. For example, a joist 101 having a cross-sectional shape having a channel for accommodating a part of a floor plate member at an upper portion as shown in FIG. That is, the lower end portion of the joist 101 may be inserted into the joist storage groove of the joist support 20, and the joist support 20 may be locked to the joist 101 using only the locking bolt member 21 and the adjustment angle 23 on one side. A joist having such a cross-sectional shape may be used at an edge of a floor surface.
[0025]
【The invention's effect】
ADVANTAGE OF THE INVENTION According to this invention, since a joist board becomes unnecessary, the number of parts can be reduced and man-hour and cost can be reduced. In addition, the joist support can be easily mounted on the joist and the position adjusting screw of the support can be operated from the floor side, so that the workability is extremely excellent.
[0026]
Since the floor member of the present invention is configured by combining a joist cut to a desired length and a floor plate member, it can flexibly cope with floors of various shapes. Further, in the floor member, since the joist and the joist support can be made of a material having excellent corrosion resistance such as metal or resin, if the material having excellent corrosion resistance is used for the floor panel member, it can be laid outdoors. . In particular, it can be suitably used for balconies with a low floor.
